Abstract:
Chelate of furancarbamide (FUR), benzoic acid hydrazide (BAH)
and its acetonebenzoic acid hydrazone (ABH) with copper II
sulphate have been prepared. The complexes and ligands were
characterized by Fourier transform infrared spectra analysis,
electronic spectra analyses, conductivity, melting point, and
solubility. The FTIR analysis indicated that the ligand (FUR)
coordinated with the metal ions through the carbonyl oxygen, the
azomethine nitrogen and amine nitrogen, while (ABH) coordinated
through the carbonyl oxygen and azomethine nitrogen. This is an
indication that the ligands acted as tridentate and bidentate
donors to the metal ions. The electronic spectra showed the
complexes as distorted octahedral geometry. The conductivity
data showed the complexes as non electrolytes. Elemental
analysis indicate that the complex of ABH formed an M:L2.
X type while FUR complex formed an ML1.X type
complex.
Key words: Benzoic acid
hydrazide acetonebenzoic acid hydrazone, furancarbamide, copper
II sulphate, complex, ligand.
